woon-SAWING. MACHINE.

Application :filed March 27, 1924. Serial No. 702,460.

To all whomz'tmag/ concern.'

Be it known that I, DANIEL R. BLAKEs- LEE, a citizen of the United States, residing at Corry, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in VV'ood- Sawing Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to motor-driven wood sawing machines and the present disclosure is directed more particularly to a drag saw.

One object of the invention is to provide a simple, inexpensive and practical machine, in which a wheeled axle constitutes a support for the driving engine and the sawing mechanism, and also acts as a drive shaft for the latter.

Another object of the invention is to provide an engine supporting frameY which is wheel-supported at one end, the other end` of the frame being adapted to support an engine when the machine is in'operation, said frame however being of such nature as to permit the engine to. be slid into close relation with the supporting Wheel or Wheels, when the machine is to be drawn from one p-lace to another. Thus, theend of the frame remote from its wheel-supported end, may be easilyl lifted and if desired connected with a wagon, truck orA the like, to be drawn from one place to another.

Another Aobject of the invention is to provideV a sawing machine in which the sawcarrying means is pivotal about the supporting axle or drive shaft, so that it may be swung toan inoperative position when the machine is to be moved from one place to another.

A still further aim is to provide lnovel connecting means between the saw-supporting means rand the axle and between the engine-carrying frame and said axle.

`Another aim is to provide a unique means forv mounting and guiding the saw.

With the foregoing and minor objects in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented Yby the accompanying drawings.

Figure 1 is a top plan view of a woodsawing machine constructed in accordance with my invention.

Figure 2 is a side elevation away and in section.

Figure 3 is an enlarged horizontal sectional view as indicated by line 3-3 of Fig. 2. l

Figure 4 is a fragmentary elevation illustrating the manner in which the saw is held in a raised .position while longitudinally shifting a log beneath said saw.

Figure 5 is a detail vertical longitudinal sectional view showing the mounting and guiding means for the saw.

Figures 6, 7, 8 and 9 are vertical transverse sectional views as indicated by lines 6 6, 7 7, sus and 9-9 of Fig. 5I

Figure 10 is a perspective view showing the preferred form of operating crank for the saw and a portion of the co-acting nitpartly broken man. -Figure 11 is a disassembled perspective View showing portions of the saw mounting vformed at its inner end with a peripheral groove 9, at its outer end with a similar `groove 10, and between the wheel spokes and the groove 9,'w1th a third groove 11'.` The grooves and 11 are engaged with sectional bearings 12 on the Vfront end of an engine- 'supporting frame 13, which frame preferably comprises a pair of parallel tracks 1-1 connected at intervals by appropriate transverse bars 15. The tracks 14 are intended to slidably support the usual skids 16 of an internal comb-ustion engine 17, and. this engine drives the shaft or axle 1, through the instrumentality -of an appropriate belt Y19 and pulleys 20, and obviously, an appropriate clutch may be provided if' desired. lVhen the machine is in operation, the engine 17 stands at approximately the rear end of the frame 13, which end may rest on the ground or other` adequate support, so that most of the weight of the engine taken from the wheels and thej` axle 1. lVhen the entire machine is to be moved vDe from one place to another however, the engine is slid forwardly into close relation with the axle l, thus permitting the rear end of the frame 13 to be easily lifted and either moved by hand or connected with a wagon, truck or the like.

I have shown forwardly converging bars 2l and 22 straddling the wheel 3 and provided at their rear ends with bearings 23 engaging the grooves 9 and 10 of the hub 7, the front ends of these bars being secured together by any suitable means, such asbolts 24. The bar 22 is preferably provided at its front end with a bolt or other anchor 25 for connecting. it to a transverse track-way 2G upon which a suitable log carriage 27 may operate, for advancing a log under the saw 28.

l have shown a longitudinal guide rod 29 pivoted at its rear end to the bar 22, as indicated at 30, the front end of said rod 2f) having an appropriate guide 3l for the saw 23. Slidable upon the rod 29, is a saw carriage, preferably in the form of a tubel 32 having` bushings in its ends, said tube beingl shown as longitudinally split at 34, so to permit it to be slightly expanded when l removing worn bushings and inserting new ones. Upon the front and rear ends of the tube 32, I have shown pairs of upstanding flanges 35 and 35a which are clamped to gether by bolts 36' and 36a. rl-lie flanges 35 are straddled by a pair of upstanding plates 37, between which the rear end of the saw 28 is secured by bolts or the like 38, and the bolts 36 preferably pass through said plates 37 as shown in Fig. 7. Also passing through these platesand through the flanges 35, is a short sleeve 39 which may well be threaded in place, said sleeve receiving a lateral stud 40fon the end of a pitman 4l. This pitman is connected with a wrist pin 42 on a balanced crank 43 secured to one end of the axle l. The crank 43 is preferably, although not necessarily of the type shown. It will be seen that when the engine 17 is operated, the axle l is rotated to operate the crank 43, thus reciprocatingl the pitman 41 and causing corresponding movement of the carriage 32- and sawv 2S. lNhenever, it is necessary toV advance the log beneath the saw, the latter may be raised and held in raised position by the pivoted prop 44, shown more particularly in Figs. 2v and 4, said prop being pivoted at 45, to the bar 22 and being engageable at its upper end with a pin 46v extending laterally from the sawy guide 3l. When the machine is to be moved from one place to another, the bars 2l and 22 and associated part-s may be swung rearwardly into compact relation with the frame V13, the engine 17l may ber moved to the front endl of this frame, and the rear end of the latter may be then easily lifted and manipulated in any desired manner.

Excellent results are obtainable from the details disclosed and they may therefore be followed if desired, but within the scope of the invention as claimed, numerous minoi changes may be made.
